vices', combinations of devices and arrangement of parts hereinafter described and defined in the claims.

Theluse of four-wheel brakes makes it desirable that a sanding device should be ar'- 10 ranged to deliver sand in front of the front wheels of the vehicle, and moreover, the oscillatory movements of the front or steering wheels makes it important that the delivery of sand should always be in front of the line l5 of travel of the front wheels whether the vehicle is travelling straight ahead or on a curve.

My invention meets these desirable features and utilizes the sand container as a front bumper. This location of the sand container in the 'position of a front bumper places the container where it will be subject to continuous vibration which is desirable to keep the sand shaken up and in loose condition for ready flowing action through controlling valves that lead to delivery spouts, the latter being mounted to oscllate and having connections to the front wheels whereby the spouts will be given the required oscillatory movements necessary for the deliveryfof sand in front of the front wheels whether travelling straight ahead or on a curve.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a front elevation with some parts broken away and some parts sectioned il- 40 lustrating the invention applied to an automobile; l

Fig. 2 is a plan view showing the front portion of the running gear of the automobile and illustrating the invention applied thereto in the manner above generally indicated;v

Fig. 3 is a View vpartly in vertical diagram and partly in vertical section taken on the line 3 3 of Fig. 2,; and

Fig. 4 is a bottom plan view of the combined sanding device and bumper.

Of the parts of the automobile, it is only desirablefor the purpose of this case to particularly note the body 5, the main frame 6, the front axle 7, steering knuckles 8 and front wheels 9. The container for dry sand y is in the form of a hollow transversely elongated box 10 preferably of sheet metal that is rigidly but detachably secured by brackets 11 to the front ends of the side bars of the main frame 6. Since this box is to be used as the front bumper. it is preferably provided with a surrounding band 12 which may be ofapliable material such, as rubber, leather or canvas. On its top and approximately at the center, this box is provided with a filling spout 13 normally closed by a cap 14. The bottom of the box is preferably inclined outward in both directions from its center and, as shown, this arrangement is afforded by a false bottom 10a applied as best shown in Fig. 1 so that the sand will run in opposite directions from the center toward the opposite ends of the box. In the bottom of the box near its ends in front of the front wheels are sand discharge passages 15 that deliver to discharge sleeveslG which have flanged upper ends rig- 1dly secured to the bottom of the box.

Mounted in the flanged upper ends of the sleeve 16 are oscillatory discharge valves 17 that normally7 close the discharge passages 15 that are provided with ports 18 that co-operate with ports 19 in the sleeves. As shown, coiled springs 2() applied to pivot bolts 21 keep the valves 17 frictionally sealed aga-inst the flanged upper ends of the co-operating sleeves 16.

to the-bottom of the box 10 and having a slot 9 and pinl connection with the connecting rod v25. The other end ofthe bell-crank 26, by a link of connectingrod v27, is connected to an arm 28 that promets from one of the steering knuckles 8.

Of vvcourse, the two steering knuckles of the automobile are, by thevusual means, cross-connected so that the front wheels move in parallel. The valves 17 are provided With rearwardly-projecting arms 28a that workthrough clearance passages in the flanged upper ends of the sleeves 16 so that by oscillatory movements of the arms 28a, valves 17 may be moved from their normal positions in which they close the ports 18 and 19 into positions in which said ports 18 and 19 are caused to register and thereby permit a discharge of sand from the box through the delivery spouts. The two arms 28 are connected by a link or connecting rod 29. A coiled spring 30 is applied around the rod 29 and is arranged to react against a yflange 31 on the bottom of the box 10 and a collar 32 on said rod 29. This spring exerts a yielding force that normally holds the two valves 1-7 in port-closing positions. Y

As a means for moving the rod 29 against the tension of the spring 30 so as to set the valve 17 into port-closing` positions for the,

delivery of sand, a suitable connection operatingfrom the drivers seat ot' the automobile is provided. As shown, this connection includes a flexible cable 33 attached to a lug 34 on rod 29 and passed over suitable guides including a sheave 35 mounted on a bracket 36 secured to the back of the box 10. Extreme movement of the rod 29 toward the right in respect to Fig. 4 is limited by a lug 37 on the rod 29 arranged to engage the flange 31.

lVith the arrangement described, when the front wheels of the automobile are set for straight ahead tra-vel, the delivery spouts 22 will be turned directly rearward in position to discharge sand directly in front of the front wheels. wheels are turned for travel toward one side or the other, as, for example, illustrated by dotted lines in Fig. 2', the delivery spouts 22 will be turned in the same direction and will be positioned at all times for the delivery of sand directly in front of the line of travel of the front wheels. In fact, in all-positions of the front wheels, the spouts will be automatically turned for delivery ot' sand directly in front thereof on the line of travel for which they are set. Obviously, the spouts. will be automatically oscillated regardless "ot" whether or not there is a delivery of sand and the delivery of sand Will be, at the will of the driver who .may manipulate the cable 33 or other connection either by the hand or footoperating device. The efliciency of the device described is thought to be obvious and it will, of course, be

understood that the device described is capable"`of various modifications without departing from the spiritof the invention herein disclosed and claimed.

What I claim is:

1-. The combination with a motor propelled r vehicle, of a sand container applied in front When, however, the front" thereof, said sand container being extended completely across the front end of the vehicle and serving as a front bumper.

2. The combination with a motor propelled vehicle, of a sand container applied in front thereof, said sand container being extended completely across the front end of the vehicle and serving as a front bumper, said container having` discharge spouts arranged to discharge-sand in front of the front wheels.

3. The combination with a motor propelled vehicle, of a sand container supported thereby ahead of the front wheels and having valve-equipped spouts for the delivery of sand in front of the frontwheels, said sand container being extended completely across the front of the vehicle and serving as a front bumper.

- 4. The combination with a motor propelled vehicle having oscillatory front steering wheels, of a lsand container carried by the said vehicle and provided with oscillatory discharge spouts with connections to the front wheel support whereby said spouts will be oscillated when said steeringvwheels are oscillated and will deliver sand in front and on the line of travel of said front steering Wheels. 5. The combination with a motor propelled vehicle having oscillatory front steering wheels, of a sand container carriedy byy the said vehicle and provided with oscillatory discharge spouts with connections to the front wheel support whereby said spouts will be oscillated when said steering wheels are oscillated and willdeliver sand in front and on the'line ,of travel of said front steering wheels, normally closed valves .interposed between said sand container and oscillatory" spouts, and means operative at will to open said valves and cause a discharge of sand through said spouts. v v

6. The combination with a motor propelled vehicle having oscillatory front knuckles and front steering wheels j ournaled thereon, of a box-like sand container carried by the vehicley in front ofthe front wheels thereof, valve-equipped discharge sleeves leading from the bottom of said container, oscillatory delivery spouts applied to said sleeves in front ofthe respective steering wheels, arms projecting from said spouts, a. link connecting said arms whereby said spouts will be given simultaneous oscillatory movements, and a connection between said link and one ot' the steering knuckles arranged to oscillate said, spouts so that they will deliver in front of said`steering wheels 'on the line of travel thereof whether running straight ahead or on curves.

In testimony whereof'I aliix my signature.
